1 and 1 Webmail Login: How to Access Your IONOS Email in 2025

Anyone who’s ever managed a 1 and 1 webmail account might feel lost after the rebranding to IONOS — the login pages look different, the app name changed, and suddenly there are three different URLs to remember, but over 8 million users still rely on these accounts and the core credentials and server settings never changed. The following covers every access method, what the rebrand shifted, and how to log in smoothly.

Active 1&1 email users worldwide: Over 8 million ·
Year 1&1 rebranded to IONOS: 2019 ·
Supported email clients: Outlook, Thunderbird, Apple Mail, and more ·
Mobile app availability: Android and iOS via IONOS Mail app

Seven key facts, one pattern: The same email credentials you had in 2018 still work — only the doors changed.

The pattern: IONOS deliberately kept three distinct entry points — webmail, product access, and account management — to avoid confusing its 8 million users during the transition. The trade-off? New users often don’t know which URL is for what.

How do I log in to 1and1 webmail?

What is the 1and1 webmail URL?

• Open mail.ionos.com in any browser — IONOS Help (official support) confirms this is the primary path for logging into Webmail with an IONOS email address.
• Alternatively, id.ionos.com/identifier (IONOS Product Login (official portal)) serves as a direct product login for mailbox access.

Do I need my IONOS customer ID or email address?

• You log in with your full email address (e.g., user@domain.com) and password — no customer ID required.
• Legacy 1&1 accounts use the same credentials on the IONOS login pages (IONOS Help (easy webmail login)).

The implication is clear: the rebrand changed the labels, not the access.

How do I reset my 1&1 webmail password?

What information do I need to reset the password?

• Visit login.ionos.com and click “Forgot password” — the official IONOS Login portal handles this.
• You need access to the recovery email or phone number registered on the account (IONOS Help (password recovery flow)).
• Legacy 1&1 accounts follow the same IONOS reset procedure.

Can I reset via the IONOS app?

• Yes — the IONOS Mail app redirects to the same reset page, requiring recovery email/phone access.
• Resetting your password does not affect stored emails or folder structures.

The takeaway: keep your recovery contact current to avoid access issues.

How do I access the 1 and 1 webmail control panel?

What can I do in the control panel?

• The control panel at login.ionos.com lets you manage email accounts, aliases, forwarders, and storage limits.
• Webmail itself — reading and sending messages — is at mail.ionos.com or via the product login at id.ionos.com/identifier.

Is the control panel the same as the webmail interface?

• No. The control panel and webmail are separate interfaces with distinct purposes (IONOS Login (customer portal)).
• Legacy 1&1 users still access the same control panel post-rebrand (IONOS Help (brand continuity)).

The trade-off: New users find having separate URLs confusing, but the separation keeps account management isolated from email reading — crucial for businesses managing multiple mailboxes.

The pattern: distinct entry points for distinct tasks, deliberate design.

How do I download the IONOS webmail app?

Is the app available for both Android and iOS?

• Search for “IONOS Mail” (formerly “1&1 Mail”) on Google Play or the Apple App Store.
• The app supports push notifications, calendar sync, and multiple mailbox management (Google Play Store (official app listing)).

What are the app features?

• Push notifications for new messages and calendar events.
• Manage multiple IONOS email mailboxes from a single app.
• Requires an active IONOS or legacy 1&1 email account.

The implication: the app centralizes management across mailboxes.

What is my IONOS email address?

How do I find my email address in my account?

• Log into the IONOS control panel (login.ionos.com) and navigate to “Email” to see all mailboxes.
• Legacy 1&1 customers may have @1and1.co.uk or @1and1.com addresses — these remain active (IONOS Help (legacy accounts)).

Can I create additional email addresses?

• Yes, up to the number of mailboxes in your plan — managed via the control panel.
• Custom domain users have addresses like username@your-domain.com.

The catch: legacy addresses remain functional, but verify your plan limits.

Timeline

• 1997 — 1&1 Internet founded; email hosting service launched.
• 2019 — 1&1 rebranded to IONOS, merging global services under one brand.
• 2020 — Legacy 1&1 login URLs redirect to IONOS; mobile app renamed from “1&1 Mail” to “IONOS Mail”.
• 2023 — Two-factor authentication rolled out for IONOS accounts including webmail (IONOS Help (2FA rollout)).

The pattern: gradual transition, still ongoing.

Clarity section

Confirmed facts

• 1&1 webmail is now managed under the IONOS brand
• The login page is mail.ionos.com for webmail
• IMAP and SMTP settings have not changed after rebranding (IONOS Help (Apple Mail setup))
• Password reset requires access to recovery email/phone (IONOS Login (password reset))

What’s unclear

• Exact timeline for shutdown of legacy 1&1 login page (if any)
• Whether legacy @1and1.com email addresses will eventually require migration
• Exact number of active users beyond 8 million
• Whether IONOS will change IMAP settings in future

Quotes

“Enter your IONOS email address and password at mail.ionos.com.”

— IONOS Help Center (official support)

“Optimized for 1 & 1 mail. Mobile access to your 1 & 1 mailbox.”

— Google Play Store listing (IONOS Mail app)

Summary

The 1&1-to-IONOS rebrand changed the logos and URLs but not the core access method. For active users with legacy @1and1.com addresses, the implication is clear: keep your recovery contact up to date, and bookmark mail.ionos.com — or risk being locked out when the old login page finally goes dark.
